Ctrl Command set_scanahead_line_params
Function Only for scan systems with SCANahead technology, for example, the excelliSCAN.
Influences the quality of marking results at runtime.
Smaller percent values increase throughput at the expense of quality.
Call set_scanahead_line_params( CornerScale, EndScale, AccScale )
Parameters CornerScale Corner sharpness with mark/mark sequences in percent.
100% = sharp corners.
As an unsigned 32-bit value.
EndScale Marking accuracy at mark/jump and jump/mark transitions.
100% = straight line ends.
As an unsigned 32-bit value.
AccScale Determines the portion of the acceleration time (not: distance traversed)
in which the laser is active, in percent. 100% = entire acceleration time.
As an unsigned 32-bit value.
Comments • Only values from 0% to 100% are useful. Higher values do not improve quality
(that is, corners cannot be even sharper than sharp), but instead only extend marking
times.
• If set_scanahead_params has not been already called, then the values only get stored,
but not applied.
• The parameters CornerScale and EndScale only affect the galvanometer scanner
positioning. They do not affect points in time when the laser is to be switched on and
off.
• The parameter AccScale only affects points in time when the laser is to be switched on
and off. It does not affect the galvanometer scanner positioning!
• If Sky Writing is activated, only the parameter EndScale is effective.
• The other parameters CornerScale and AccScale are not applied – except there is no
genuine Sky Writing movement:
– If Sky Writing Mode 3 is activated and the angular limit is undercut, CornerScale is
effective.
• The parameter EndScale is effective, if Sky Writing is activated (here, the following
applies as well: smaller percent values increase throughput at the expense of quality).
